Description

Technical Field

[0001] The utility model relates to the technical field of detecting the torsion angle generated by continuous wires during transportation, in particular to an online torsion detection device for a wire grinding machine. Background Art

[0002] A wire outer surface grinder is a device that can continuously grind the outer surface of a wire to remove surface defects of the wire during the continuous online conveying process. Usually, a wire outer surface grinder is provided with multiple grinding wheels that rotate at high speed along the wire conveying direction, and usually multiple grinding wheels are arranged in pairs in the wire conveying direction. Such a wire outer surface grinder is usually suitable for processing relatively static wires that are continuously conveyed and have no self-twist. In this way, the grinding position of each pair of grinding wheels is usually a fixed position on the circumference of the wire. If the continuous wire is twisted due to its own stress during the conveying process, the grinding position of each pair of grinding wheels will deflect as the wire twists, which causes the grinding wheel to gradually deviate from the preset grinding position during the grinding process. In order to solve this problem, it is necessary to measure the amount of torsion generated by the continuous wire during the conveying process, and then correct the grinding position of the grinding wheel according to the torsion to make the wire outer surface grinder adapt to various wire grinding conditions. Therefore, it has become an inevitable trend for technicians in this field to develop an online torsion detection device for a wire grinder that can measure the torsion of the wire during the continuous conveying of the wire.
